Steel stamps are an ideal option for making a touchmark because they offer a long-lasting, cost-effective tool that can be easily customized. Adding a touchmark is often one of the last steps in the creation process, so it is critical that the mark is made correctly. Over the years we've helped many artisans and craftspeople make their unique touchmark, and we've created a step-by-step guide for making the perfect touchmark.
Before ordering your stamp or picking up a hammer, spend some time planning your touchmark design. This upfront work prevents costly mistakes and ensures your mark will be legible and professional for years to come.
Complex designs rarely translate well to small stamps. Thin lines disappear, intricate details blur together, and busy artwork becomes unreadable when stamped. Your touchmark should be recognizable at a glance, even when stamped as small as 1/8 inch.
The size of your touchmark should match the items you create most often. Knife makers typically use 1/8" to 3/16" tall characters, while blacksmiths working on larger pieces might go up to 1/2". Remember that smaller stamps require more precision in striking, while larger stamps need significantly more force. If you work across a range of piece sizes, consider ordering multiple stamp sizes rather than trying to make one size work for everything.
Beginners often choose designs with letters too close together, which can cause characters to blend when stamped into softer materials. Leave adequate spacing between elements. Serif fonts, while attractive, can be problematic in small sizes where the thin serifs may not stamp clearly. Sans-serif fonts typically provide better results for touchmarks.
The first step in making a touchmark is acquiring a steel hand stamp or die, a hammer or press, and a solid work surface.
If using a hand stamp and hammer to make your touchmark, it is essential not to overlook the quality of your materials. Look for a high-quality steel hand stamp that will resist spalling when hit. A hand stamp holder can also be useful when hand stamping because it protects your hands and helps to ensure your safety.
An often overlooked part of the hand stamping process is the surface on which you will be stamping. You should choose a solid and stable surface, like a workbench, and, ideally, locate a support or leg and make your mark over it. Supports and legs will provide the greatest stability, which is essential to prevent bouncing or flexing of the bench surface, both of which can impact the clarity of the mark. Finally, placing a large, flat piece of soft steel on your bench and laying your piece on top of it, rather than on the bench itself, is preferable.
It is also important to select the correct hammer when hand stamping. Choose the proper marking hammer size based on the following criteria: if you're marking a single 1/4" tall character into mild steel, you'll need approximately 2.1 tons of pressure. In this example, we recommend using our O.E. hammer with 1 lb. weight. Experienced operators can typically use a lighter marking hammer (3/4 lb. in this case). If you're unsure about what hammer is best for your touchmark, the manufacturer of the steel hand stamp should be able to provide you with a recommendation.
Different metals require different approaches to achieve clean, consistent touchmarks. Understanding these differences prevents damaged stamps and ensures professional results regardless of the material you're marking.
These materials stamp relatively easily and provide excellent contrast. Use standard sharp-face stamps with moderate hammer force. The metal deforms predictably, creating crisp impressions with well-defined edges. Most craftspeople start here because it's forgiving and responds well to varying hammer weights.
Stainless steels work-hardening properties make it more demanding to stamp. You'll need a heavier hammer than you'd use for mild steel, and the first strike must be decisive. Multiple light taps will work harden the surface, making subsequent strikes ineffective.
Aluminum stamps beautifully but requires a lighter touch. The material is soft enough that excessive force can cause the stamp to sink too deeply, creating raised edges around your mark. These raised areas are difficult to file down without affecting the touchmark itself. Start with lighter hammer blows and increase force gradually until you achieve the desired depth.
The first step to making a touchmark is to place the object you are going to mark on your steel base. Next, place the hand stamp onto the part and rock it back and forth. The key here is to ensure that the stamp is laying perfectly flat on the part.
Next, carefully strike the stamp firmly with the hammer (this would be a good time to practice on some scrap material before marking your finished part). If you aren't careful, the hammer can strike the stamp more than once. When the hammer strikes multiple times, you will end up with double or triple impressions.
A few notes about striking the stamp. First, the speed with which you hit the stamp and the accuracy with which the hammer impacts the stamp is crucial to a successful mark. You want a touchmark that has consistent depth across the entire mark and is clear on the piece. The proper speed and accuracy are essential to achieving this. Second, if you're marking multiple characters by utilizing steel type and a handheld type holder, the amount of striking force required to make a clear mark is going to be increased dramatically. Again, we recommend taking the time to practice so that you can get the 'feel' for how hard to strike the stamp and learn to control the hammer, so it only strikes once.
Even experienced craftspeople encounter problems when making touchmarks. Knowing how to diagnose and fix these issues saves time, materials, and frustration.
When your touchmark appears faint or doesn't stamp completely, several factors could be at play. Most commonly, you're not hitting the stamp hard enough or the stamp isn't sitting perfectly flat on the workpiece. Check that your work surface is solid and that you're striking directly over a bench leg or support. Curved or uneven surfaces require more careful alignment and may need custom fixtures to hold the work steady.
This frustrating problem usually occurs when the hammer bounces off the stamp and strikes again. Practice your hammer technique on scrap material, focusing on pulling the hammer away immediately after impact. Some craftspeople find success using a slightly heavier hammer, which reduces the tendency to bounce. If you're consistently getting double strikes, examine your hammer face for damage or wear that might be causing erratic bouncing.
Tiny chips in your stamp face will show up as light spots in every subsequent mark. This typically happens when stamps are struck against hardened surfaces or when using hammers with damaged faces. Always use a proper steel base under your work, never stamp directly on a hardened anvil face. Replace chipped stamps immediately, as continued use will only worsen the problem and potentially damage your finished pieces.
When part of your touchmark appears deeper than other areas, the stamp likely wasn't perfectly flat against the work surface. This is particularly common when marking curved pieces or when the workpiece isn't properly supported. Take extra time to ensure full contact before striking. For curved surfaces, consider having a custom stamp made with a matching curve.
While hand stamping works for most touchmark applications, understanding when other methods might serve you better can save time and improve results.
Hot stamping with branding irons works exceptionally well on wood handles, leather sheaths, and some plastics. The process is gentler than impact stamping and allows for marking materials that would be damaged by hammer blows. If you're marking wooden handles or creating leather goods, hot stamping produces clean, professional results without the risk of splitting or cracking.
Craftspeople who mark dozens of pieces regularly should consider a small marking press. Presses provide consistent pressure and eliminate the variables introduced by hand hammer technique. They're particularly valuable when marking multiple identical pieces or when working with materials that require precise, repeatable force application.
Proper safety practices and tool maintenance ensure consistent results and prevent accidents in your workshop.
Always wear safety glasses when stamping, regardless of the material. Flying metal particles, while rare, can cause serious eye injury. Keep your non-striking hand well clear of the stamping area and never attempt to steady a stamp with your fingers. Stamp holders exist for a reason. Ensure your work area has adequate lighting so you can clearly see what you're doing.
Before each use, examine your stamps for chips, cracks, or mushrooming on the striking end. Small chips in the stamp face will show up as light spots in your touchmarks. Mushrooming on the striking end indicates the stamp has been hit too hard or with an improper hammer, and the expanded metal poses a safety hazard as pieces can break off during striking.
Store stamps in individual protective sleeves or blocks to prevent the engraved faces from striking each other. Even small nicks from tool-on-tool contact will affect your mark quality. Keep hammers hung up or in dedicated holders where the striking faces won't contact other tools. A damaged hammer face will affect every mark you make.
Clean stamp faces periodically to remove any metal buildup from marking operations. This buildup can cause incomplete impressions and will worsen over time if not addressed. Keep a light coating of oil on stored stamps to prevent rust but clean them before use to avoid oil interfering with the marking process.
Replace worn tools before they affect your work quality. A stamp that's beginning to show wear will still make acceptable marks for a while, but the degradation is progressive. It's better to replace tools proactively than to discover problems when marking a finished piece.
